Cardiovascular Imaging

A polio-like condition called acute flaccid mylelitis (AFM) that causes partial paralysis is showing up in children across the U.S. and can only be detected with MRI and spinal fluid tests, according to a report published Oct. 8 by NBC News.

International researchers have created an artificial intelligence (AI) method capable of automatically quantifying left ventricle (LV) function from cine MRIs, according to a multivendor, multicenter study published Oct. 9 in Radiology. Experts believe it may lead to faster cardiac MRI reporting.

Measuring wall thickness in carotid arteries with MRI may help better determine cardiovascular disease risk assessment, according to research published Oct. 9 in Radiology.

The American College of Radiology (ACR) has named breast imaging researcher Etta Pisano, MD, chief research officer of the ACR, the first woman in ACR's history to hold the position.

Cardiac chamber enlargement can be identified with high specificity and reasonable sensitivity on axial chest CT images by use of gender-specific measurement thresholds, according to new research published in the American Journal of Roentgenology.

International researchers from the Child Mind Institute in New York have released non-human primate brain imaging data sets aimed to develop wiring diagrams and improve the understanding of brain disorders in humans.  

Heart attack and other life-threatening cardiovascular events can be predicted with CT-based measures of calcification in the abdominal aorta and could be a more accurate predictive model than the widely known Framingham risk score, according to research published Oct. 2 in Radiology.

SPECT myocardial perfusion imaging (MPI) and deep learning have proven to be a powerful pair in predicting obstructive coronary artery disease (CAD) and improving the interpretation of upright and supine images, according to research published Sept. 27 in the Journal of Nuclear Medicine.

As imaging scans before widely more available and affordable, more Americans are getting more tests than they used to—currently totaling to more than 85 million CT scans each year, according to an article published Oct. 1 by The Washington Post. But how much is too much radiation?

A new protocol—HEART Pathway—can identify low-risk emergency department patients with chest pain who can be discharged without stress testing or angiography, according to results of a Sept. 28 study published in Circulation.

Intravascular ultrasound (IVUS)-guided stent implantation produced better clinical outcomes for heart patients compared to a conventional angiography-guided method, said researchers this week at the Transcatheter Cardiovascular Therapeutics (TCT) meeting in San Diego, California.

Fractional flow reserve (FFR) measured using coronary angiogram achieved greater diagnostic accuracy compared to invasive pressure-wire, according to a 10-center study published in Circulation.
